SAFC2 - wiring help please - URGENT

[skysaresilver]

hey guys,

just got a brand new safc2 the other week and i'm wanting to install it myself, but cannot read japanese (funny that)... does anyone know of a website (tried apexi usa - no help as they only have the original safc documentation) or can help tell me where what wire needs to go where into the ecu, i already know what ecu i have and where each needs to be wired up, i'm just stuck on the actual wires from the unit and what each colour represents in relation to where it goes in the ecu..... i have sourced out this much sofar by myself can someone tell me whether i'm on the right track or not....

my ecu is N4-a - (1994 R33 gts-t series 1)

of the six wires i understand that need to be wired up.....

RED = IG Power

GREEN = RPM signal

BLACK = Ground

YELLOW = Airflow/Pressure Signal OUTPUT

WHITE = Airflow/Pressure Signal INPUT

BROWN = ???

on the ecu diagram it has RPM Signal, Ground, Airflow Signal, Throttle Signal and IG Power - (so that's only 5 connections and from what i understand i have one connection going nowhere, one too many airflow/pressure signals and no throttle signal...

many thanks

(now i'm really confused - just didn't think i should stuff something up which has to be connected to the ecu).:uh-huh:

the brown wire is also a 'ground' it goes on the same wire as the black wire however it is to be tapped in closer to the ecu from memory.

You should also have one wire that goes to the knock sensor, you have a choice of two. In the diagram you will notice a (1) and a (2) pinout from the ecu. The best choice is the number 1 knock sensor.

If you do a search in the forced induction thread you will find the wiring codes.

thanks rev210 - that was heaps of help

i installed one of these myself as well, and what i did was install the japanese character set on my web browser and i went to the altavista translator site and used that...

[rev210]

Red = IG power

Brown = GND #1, closer to ECU

Black = GND #2

Grey = TPS signal

Wite = MAF input

Yellow = MAF output

Blue = 2nd MAF for twins

Green = Tacho/RPM signal

Purple = knock

try searching next time.....

guys please help.

im installing my new s-afc today only problem is i cant locate the rpm signal wire on the ecu. the diagram off the apexi website tell me the location of the wire, but there is no wire there???????

maybe its cause mine is an auto?

anyone know where the rpm signal wire is on the ecu in an auto r33 gts-t series 1
